Description Steve Snyder 2005-10-29 14:28:35 UTC

From Bugzilla Helper:
User-Agent: Opera/8.5 (X11; Linux i686; U; en)

Description of problem:
Starting with the standard configuration (file /boot/config-2.6.9-22.0.1.EL, 
from the i686 kernel RPM) I deselected ACPI support in "make menuconfig".  When 
building the kernel I received the link error shown below.

Version-Release number of selected component (if applicable):
kernel-2.6.9-22.0.1.EL

How reproducible:
Didn't try

Steps to Reproduce:
1.  Unpack and prep the standard source in the usual way:

  rpm -i /tmp/kernel-2.6.9-22.0.1.EL.src.rpm
  rpmbuild -bp --target i686 SPECS/kernel.spec

2. Run "make menuconfig" against standard kernel config file, deselect ACPI

3. Build kernel
  

Actual Results:    LD      init/built-in.o
  LD      .tmp_vmlinux1
arch/i386/kernel/built-in.o(.init.text+0x1518): In function `setup_arch':
: undefined reference to `acpi_boot_table_init'
make: *** [.tmp_vmlinux1] Error 1


Expected Results:  The kernel build should not reference device support that I have disabled.

hi,

We don't support rhel4 kernels re-compiled with alternative configurations.

thanks.

Comment 2 Jason Baron 2005-11-01 15:26:36 UTC

perhaps acpi=off on the kernel command line will get you what you want?

Comment 3 Steve Snyder 2005-11-01 18:21:33 UTC

Well, I'm not terribly upset by the inability to deselect ACPI.  I can't use 
ACPI, so I thought I'd save a little memory by removing the ACPI support 
altogether.  Doing acpi=off does indeed quiet the boot-time complaints.

I just filed this report because I thought you would be interested that the ACPI 
option is no longer optional.
